Medical mask mold manufacturing requirements:

Medical mask molds are very demanding molds, and the product inspection standards are extremely high. In addition to high-precision processing, it is necessary to understand the usefulness of this product and the inspection standards of the Quality Supervision Bureau.

First of all, the steel material of the mold is selected. The mold should be selected with high hardness. Steel materials with HRC above 35 ° are more suitable. Generally, nak80 / S136 steel materials are used. The mold has a small degree of thermal deformation and good discharge properties.

Secondly, the control of processing accuracy is particularly important. Because the puncture needle product is very small, the size of the small hole is only 1mm in diameter, and the concentricity of the core must be ensured. This is a test of the accuracy of mold processing personnel and processing equipment. . The needle needs to be made of copper electrodes. It is not easy to wear. After the high-speed carving is in place, the matching mold is then used to hit the mirror with electric sparks (here we should pay attention to the processing of spark gaps).

Third: the choice of glue mouth. Generally, this product will use a multi-cavity planning structure. The mold uses imported warm runner to convert the ambush glue. Because the glue mouth is on the inclined surface, it is easy to present the condition of the glue mouth. EDM is particularly important, and the spark gap should be within 0.01 as much as possible.

Precautions:

If this mold is over-cut after processing, the small inserts are basically scrapped directly, and the processing volume is also large.
